Tensions run high as genius Sherlock Holmes, astute Dr. John Watson, brilliant detective Luther and first-rate DSI Gibson team up to solve a murder (and promote their shows). The BBC is getting ready for what looks to be an exceptional season of crime dramas. Thanks to this promo, fans no longer have to imagine what it would be like if all of these bad-ass characters worked together. As expected, it would be awesome!

Benedict Cumberbatch and Martin Freeman, from “Sherlock,” will return for a holiday special and then Season 4 of this contemporary version of Sir Arthur Conan Doyle’s classic detective stories. Idris Elba is back in a special presentation of “Luther” where he will continue to prey on murderers, and Gillian Anderson returns to hunt down killers in Season 3 of “The Fall” soon, as well. Bad guys are gonna get got this new year.

The “Luther” one night, two-hour special debuts December 17 on BBC America. “Sherlock: The Abominable Bride” premieres January 1, 2016, and “The Fall” returns to the BBC in 2016. Watch the mash-up above.
